In Chinese daily language, excellent and outstanding people are compared to a dragon, while incapable people with no achievements are compared with other, disesteemed creatures, such as a worm. A number of Chinese proverbs and idioms feature references to a dragon, such as "Hoping one's son will become a dragon" (simplified Chinese: 望子成龙; traditional Chinese: 望子成龍; pinyin: wàng zǐ chéng lóng).

Historically, the dragon was associated with the Emperor of China and used a symbol to represent imperial power. The founder of Han dynasty Liu Bang claimed that he was conceived after his mother dreamt of a dragon.[2] During the Tang dynasty, Emperors wore robes with dragon motif as an imperial symbol, and high officials may also be presented with dragon robes.[3] In the Yuan dynasty, the two-horned five-clawed dragon was designated for use by the Son of Heaven or Emperor only, while the four-clawed dragon was used by the princes and nobles.[4] Similarly during the Ming and Qin dynasty, the five-clawed dragon was strictly reserved for use by the Emperor only. The dragon in the Qing dynasty appeared on the first Chinese national flag.[5]

The Chinese dragon has very different connotations to European dragon – in European cultures, the dragon is a firebreathing creature with aggressive connotations, whereas the Chinese dragon is a spiritual and cultural symbol that represents prosperity and good luck, as well as a rain deity that fosters harmony. It was reported that the Chinese government decided against using the dragon as its official 2008 Summer Olympics mascot because of the aggressive connotations that dragons have outside of China, and chose more "friendly" symbols instead.[7]

The ancient Chinese self-identified as "the descendants of the dragon" because the Chinese dragon is an imagined reptile that represents evolution from the ancestors and qi energy.[9] The presence of dragons within Chinese culture dates back several thousands of years with the discovery of a dragon statue dating back to the fifth millennium BC from the Yangshao culture in Henan in 1987,[10] and jade badges of rank in coiled form have been excavated from the Hongshan culture circa 4700-2900 BC.[11] Some of the earliest Dragon artifacts are the pig dragon carvings from the Hongshan culture.

The coiled dragon or snake form played an important role in early Chinese culture. The character for "dragon" in the earliest Chinese writing has a similar coiled form, as do later jade dragon amulets from the Shang period.[12]

Ancient Chinese referred to unearthed dinosaur bones as dragon bones and documented them as such. For example, Chang Qu in 300 BC documents the discovery of "dragon bones" in Sichuan.[13] The modern Chinese word for dinosaur is konglong (恐龍/恐龙), and villagers in central China have long unearthed fossilized "dragon bones" for use in traditional medicines, a practice that continues today.[14]

The binomial name for a variety of dinosaurs discovered in China, Mei long, in Chinese (寐 mèi and 龙 lóng) means "sleeping dragon." Fossilized remains of Mei long have been found in China in a sleeping and coiled form, with the dinosaur nestling its snout beneath one of its forelimbs while encircling its tail around its entire body.[15]

From its origins as totems or the stylized depiction of natural creatures, the Chinese dragon evolved to become a mythical animal. The Han dynasty scholar Wang Fu recorded Chinese myths that long dragons had nine anatomical resemblances.

The people paint the dragon's shape with a horse's head and a snake's tail. Further, there are expressions as 'three joints' and 'nine resemblances' (of the dragon), to wit: from head to shoulder, from shoulder to breast, from breast to tail. These are the joints; as to the nine resemblances, they are the following: his antlers resemble those of a stag, his head that of a camel, his eyes those of a demon, his neck that of a snake, his belly that of a clam (shen, 蜃), his scales those of a carp, his claws those of an eagle, his soles those of a tiger, his ears those of a cow. Upon his head he has a thing like a broad eminence (a big lump), called [chimu] (尺木). If a dragon has no [chimu], he cannot ascend to the sky.[16]

Further sources give variant lists of the nine animal resemblances. Sinologist Henri Doré lists these characteristics of an authentic dragon: "The antlers of a deer. The head of a crocodile. A demon's eyes. The neck of a snake. A tortoise's viscera. A hawk's claws. The palms of a tiger. A cow's ears. And it hears through its horns, its ears being deprived of all power of hearing."[17] He notes that, "Others state it has a rabbit's eyes, a frog's belly, a carp's scales." The anatomy of other legendary creatures, including the chimera and manticore, is similarly amalgamated from fierce animals.

Chinese dragons were considered to be physically concise. Of the 117 scales, 81 are of the yang essence (positive) while 36 are of the yin essence (negative). Initially, the dragon was benevolent, wise, and just, but the Buddhists introduced the concept of malevolent influence among some dragons. Just as water destroys, they said, so can some dragons destroy via floods, tidal waves, and storms. They suggested that some of the worst floods were believed to have been the result of a mortal upsetting a dragon.

Dragons chasing flaming pearl, Qing dynasty.

Many pictures of oriental dragons show a flaming pearl under their chin or in their claws. The pearl is associated with spiritual energy, wisdom, prosperity, power, immortality, thunder, or the moon. Chinese art often depicts a pair of dragons chasing or fighting over the flaming pearl.

Chinese dragons are occasionally depicted with bat-like wings growing out of the front limbs, but most do not have wings, as their ability to fly (and control rain/water, etc.) are mystical and not seen as a result of their physical attributes.

This description accords with the artistic depictions of the dragon down to the present day. The dragon has also acquired an almost unlimited range of supernatural powers. It is said to be able to disguise itself as a silkworm, or become as large as our entire universe. It can fly among the clouds or hide in water (according to the Guanzi). It can form clouds, can turn into water, can change color as an ability to blend in with their surroundings, as an effective form of camouflage or glow in the dark (according to the Shuowen Jiezi).

In many other countries, folktales speak of the dragon having all the attributes of the other 11 creatures of the zodiac, this includes the whiskers of the Rat, the face and horns of the Ox, the claws and teeth of the Tiger, the belly of the Rabbit, the body of the Snake, the legs of the Horse, the goatee of the Goat, the wit (or brain) of the Monkey, the crest of the Rooster, the ears of the Dog and the snout of the Pig.

In some circles, it is considered bad luck to depict a dragon facing downwards, as it is seen as disrespectful to place a dragon in such manner that it cannot ascend to the sky. Also, depictions of dragons in tattoos are prevalent as they are symbols of strength and power, especially criminal organisations where dragons hold a meaning all on their own. As such, it is believed that one must be fierce and strong enough, hence earning the right to wear the dragon on his skin, lest his luck be consumed by the dragons.[citation needed]

Chinese dragons are strongly associated with water and weather in popular religion. They are believed to be the rulers of moving bodies of water, such as waterfalls, rivers, or seas. The Dragon God is the dispenser of rain as well as the zoomorphic representation of the yang masculine power of generation.[18] In this capacity as the rulers of water and weather, the dragon is more anthropomorphic in form, often depicted as a humanoid, dressed in a king's costume, but with a dragon head wearing a king's headdress.

Because of this association, they are seen as "in charge" of water-related weather phenomena. In premodern times, many Chinese villages (especially those close to rivers and seas) had temples dedicated to their local "dragon king". In times of drought or flooding, it was customary for the local gentry and government officials to lead the community in offering sacrifices and conducting other religious rites to appease the dragon, either to ask for rain or a cessation thereof.

According to Chinese legend, both Chinese primogenitors, the earliest Door and the Yellow Emperor (Huangdi), were closely related to 'Long' (Chinese dragon). At the end of his reign, the first legendary ruler, the Yellow Emperor, was said to have been immortalized into a dragon that resembled his emblem, and ascended to Heaven. The other legendary ruler, the Yan Emperor, was born by his mother's telepathy with a mythical dragon. Since the Chinese consider the Yellow Emperor and the Yan Emperor as their ancestors, they sometimes refer to themselves as "the descendants of the dragon". This legend also contributed towards the use of the Chinese dragon as a symbol of imperial power.[citation needed]

Dragons (usually with five claws on each foot) were a symbol for the emperor in many Chinese dynasties. During the Qing dynasty, the imperial dragon was colored yellow or gold, and during the Ming dynasty it was red.[19] The imperial throne was referred to as the Dragon Throne. During the late Qing dynasty, the dragon was even adopted as the national flag. Dragons are featured in carvings on the stairs and walkways of imperial palaces and imperial tombs, such as at the Forbidden City in Beijing.

In some Chinese legends, an emperor might be born with a birthmark in the shape of a dragon. For example, one legend tells the tale of a peasant born with a dragon birthmark who eventually overthrows the existing dynasty and founds a new one; another legend might tell of the prince in hiding from his enemies who is identified by his dragon birthmark.[citation needed]

Worship of the Dragon God is celebrated throughout China with sacrifices and processions during the fifth and sixth moons, and especially on the date of his birthday the thirteenth day of the sixth moon.[18] A folk religious movement of associations of good-doing in modern Hebei is primarily devoted to a generic Dragon God whose icon is a tablet with his name inscribed, for which it has been named the "movement of the Dragon Tablet".[20]

Symbols of dragons were placed in tombs as means to get to heaven.[21] The Walters Art Museum.

Dragons or dragon-like depictions have been found extensively in neolithic-period archaeological sites throughout China. The earliest depiction of dragons was found at Xinglongwa culture sites. Yangshao culture sites in Xi'an have produced clay pots with dragon motifs. A burial site Xishuipo in Puyang which is associated with the Yangshao culture shows a large dragon mosaic made out of clam shells.[22] The Liangzhu culture also produced dragon-like patterns. The Hongshan culture sites in present-day Inner Mongolia produced jade dragon objects in the form of pig dragons which are the first 3-dimensional representations of Chinese dragons.[23]

One such early form was the pig dragon. It is a coiled, elongated creature with a head resembling a boar.[24] The character for "dragon" in the earliest Chinese writing has a similar coiled form, as do later jade dragon amulets from the Shang dynasty.

Chinese literature and myths refer to many dragons besides the famous long. The linguist Michael Carr analyzed over 100 ancient dragon names attested in Chinese classic texts.[25] Many such Chinese names derive from the suffix -long:

Zhulong (Chinese: 燭龍; pinyin: zhúlóng; Wade–Giles: chu-lung; literally: "torch dragon") or Zhuyin (Chinese: 燭陰; pinyin: zhúyīn; Wade–Giles: chu-yin; literally: "illuminating darkness") was a giant red draconic solar deity in Chinese mythology. It supposedly had a human's face and snake's body, created day and night by opening and closing its eyes, and created seasonal winds by breathing. (Note that this zhulong is different from the similarly named Vermilion Dragon or the Pig dragon).

The Black Dragon [Xuanlong 玄龍 or Heilong 黑龍] spirits, kings dwelling in the depths of the mystic waters.[26]

With the addition of the Yellow Dragon of the Center to Azure Dragon of the East, these Vermilion, White, and Black Dragons coordinate with the Four Symbols, including the Vermilion Bird of the South, White Tiger of the West, and Black Tortoise of the North.

Several Ming dynasty texts list what were claimed as the Nine Offspring of the Dragon (龍生九子), and subsequently these feature prominently in popular Chinese stories and writings. The scholar Xie Zhaozhe (謝肇淛, 1567–1624) in his work Wu Za Zu (五雜俎, ca. 1592) gives the following listing, as rendered by M.W. de Visser:

A well-known work of the end of the sixteenth century, the Wuzazu五雜俎, informs us about the nine different young of the dragon, whose shapes are used as ornaments according to their nature.

The [pulao蒲牢], dragons which like to cry, are represented on the tops of bells, serving as handles.

The [qiuniu囚牛], which like music, are used to adorn musical instruments.

The [chiwen螭吻/鴟吻], which like swallowing, are placed on both ends of the ridgepoles of roofs (to swallow all evil influences).

The [chaofeng嘲風], lion-like beasts which like precipices, are placed on the four corners of roofs.

The [yazi睚眦/睚眥], which like to kill, serve as ornaments of sword-grips.

The [bixi贔屭], which have the shape of the [chilong 螭龍], and are fond of literature, are represented on the sides of grave-monuments.

The [bi'an狴犴], which like litigation, are placed over prison gates (in order to keep guard).

The [suanni狻猊], which like to sit down, are represented upon the bases of Buddhist idols (under the Buddhas' or Bodhisattvas' feet).

The [baxia𧈢𧏡], finally, big tortoises which like to carry heavy objects, are placed under grave-monuments.

Further, the same author enumerates nine other kinds of dragons, which are represented as ornaments of different objects or buildings according to their liking prisons, water, the rank smell of newly caught fish or newly killed meat, wind and rain, ornaments, smoke, shutting the mouth (used for adorning key-holes), standing on steep places (placed on roofs), and fire.[27]

The Sheng'an waiji (升庵外集) collection by the poet Yang Shen (楊慎, 1488–1559) gives different 5th and 9th names for the dragon's nine children: the taotie (饕餮), which loves to eat and is found on food-related wares, and the jiaotu (椒圖), which looks like a conch or clam, does not like to be disturbed, and is used on the front door or the doorstep. Yang's list is bixi, chiwen or cháofēng, pulao, bi'an, taotie, qiuniu, yazi, suanni, and jiaotu.[28]

Oldest known attestation of the "children of the dragon" list is found in the Shuyuan Zaji (椒园杂记, Miscellaneous records from the bean garden) by Lu Rong (1436–1494); however, he noted that the list enumerates mere synonyms of various antiques, not children of a dragon.[29] The nine sons of the dragon were commemorated by the Shanghai Mint in 2012's year of the dragon with two sets of coins, one in silver, and one in brass. Each coin in the sets depicts one of the 9 sons, including an additional coin for the father dragon, which depicts the nine sons on the reverse.[30]

The early Chinese dragons can be depicted with two to five claws. Different countries that adopted the Chinese dragon have different preferences; in Mongolia and Korea, the four-clawed dragons are used, while in Japanese dragon three-clawed dragons are common.[31] By the Yuan dynasty, the five-clawed dragons became reserved for use by the emperor while the princes used four-clawed dragons.[4] The usage of the dragon motif was codified during the Yuan dynasty, and phoenixes and five-clawed two-horned dragons may not be used on the robes of officials and other objects such as plates and vessels.[4][32] It was further stipulated that for commoners, "it is forbidden to wear any cloth with patterns of Qilin, Male Fenghuang (Chinese phoenix), White rabbit, Lingzhi, Five-Toe Two-Horn Dragon, Eight Dragons, Nine Dragons, 'Ten thousand years', Fortune-longevity character and Golden Yellow etc."[33]

The Hongwu Emperor of the Ming dynasty emulated the Yuan dynasty rules on the use of the dragon motif and decreed that the dragon would be his emblem and that it would have five claws. The four-clawed dragon would become typically for imperial nobility and certain high-ranking officials. The three clawed dragon was used by lower ranks and the general public (widely seen on various Chinese goods in the Ming dynasty). The dragon, however, was only for select royalty closely associated with the imperial family, usually in various symbolic colors, while it was a capital offense for anyone — other than the emperor himself — to ever use the completely gold-colored, five-clawed Long dragon motif. Improper use of claw number or colors was considered treason, punishable by execution of the offender's entire clan. The convention was carried into the Qing dynasty, and portraits of the Qing emperors were usually depicted with five-clawed dragons.

The number nine is special in China as it is seen as number of the heaven, and Chinese dragons are frequently connected with it. For example, a Chinese dragon is normally described in terms of nine attributes and usually has 117 (9x13) scales - 81 (9x9) Yang and 36 (9x4) Yin. This is also why there are nine forms of the dragon and there are 9 sons of the dragon (see Classical depictions above). The Nine-Dragon Wall is a spirit wall with images of nine different dragons, and is found in imperial Chinese palaces and gardens. Because nine was considered the number of the emperor, only the most senior officials were allowed to wear nine dragons on their robes — and then only with the robe completely covered with surcoats. Lower-ranking officials had eight or five dragons on their robes, again covered with surcoats; even the emperor himself wore his dragon robe with one of its nine dragons hidden from view.

There are a number of places in China called "Nine Dragons", the most famous being Kowloon (in Cantonese) in Hong Kong. The part of the Mekong in Vietnam is known as Cửu Long, with the same meaning.

The Dragon is one of the 12 animals in the Chinese zodiac which is used to designate years in the Chinese calendar. It is thought that each animal is associated with certain personality traits. Dragon years are usually the most popular to have children. There are more people born in Dragon years than in any other animal years of the zodiac.[citation needed]

The Azure Dragon - Qing Long - 青龍 is considered to be the primary of the four celestial guardians, the other three being the Zhu Que - 朱雀 (Vermilion Bird), Bai Hu - 白虎 (White Tiger), Xuan Wu - 玄武 (Black Tortoise-like creature). In this context, the Azure Dragon is associated with the East and the element of Wood.

At special festivals, especially the Duanwu Festival, dragon boat races are an important part of festivities. Typically, these are boats paddled by a team of up to 20 paddlers with a drummer and steersman. The boats have a carved dragon as the head and tail of the boat. Dragon boat racing is also an important part of celebrations outside of China, such as at Chinese New Year. A similar racing is popular in India in the state of Kerala called Vallamkali and there are records on Chinese traders visiting the seashores of Kerala centuries back (Ibn Batuta).

On auspicious occasions, including Chinese New Year and the opening of shops and residences, festivities often include dancing with dragon puppets. These are "life sized" cloth-and-wood puppets manipulated by a team of people, supporting the dragon with poles. They perform choreographed moves to the accompaniment of drums, drama, and music. They also wore good clothing made of silk.

In many Buddhist countries, the concept of the nāga has been merged with local traditions of great and wise serpents or dragons, as depicted in this stairway image of a multi-headed nāga emerging from the mouth of a Makara in the style of a Chinese dragon at Phra Maha Chedi Chai Mongkol on the premises of Wat Pha Namthip Thep Prasit Vararam in Thailand's Roi Et Province Nong Phok District.

The tiger is considered to be the eternal rival to the dragon, thus various artworks depict a dragon and tiger fighting an epic battle. A well used Chinese idiom to describe equal rivals (often in sports nowadays) is "Dragon versus Tiger". In Chinese martial arts, "Dragon style" is used to describe styles of fighting based more on understanding movement, while "Tiger style" is based on brute strength and memorization of techniques.[citation needed]

As a part of traditional folklore, dragons appear in a variety of mythological fiction. In the classical novel Journey to the West, the son of the Dragon King of the West was condemned to serve as a horse for the travellers because of his indiscretions at a party in the heavenly court. Sun Wukong's staff, the Ruyi Jingu Bang, was robbed from Ao Guang, the Dragon King of the East Sea. In Fengshen Yanyi and other stories, Nezha, the boy hero, defeats the Dragon Kings and tames the seas. Chinese dragons also appear in innumerable Japanese anime movies and television shows, manga, and in Western political cartoons as a personification of the People's Republic of China. The Chinese respect for dragons is emphasized in Naomi Novik's Temeraire novels, where they were the first people to tame dragons and are treated as equals, intellectuals, or even royalty, rather than beasts solely bred for war in the West. Manda is a large Chinese dragon that appears in the Godzilla storyline. A golden three-headed dragon also appears in the comic book series God Is Dead.

Red dragon is a symbol of China which appears in many mahjong games.

A Chinese Water-Dragon is used as the main antagonist in Season 3 of the Australian television series Mako Mermaids. The Dragon is heavily based on Chinese Mythology to coincide with a new Chinese mermaid on the show.
